Preheat your oven to 425°F and line a rimmed baking sheet with parchment paper.
Pat the chicken thighs completely dry with paper towels to ensure the skin becomes perfectly crispy during roasting.
Mince the garlic cloves and finely chop the fresh rosemary and thyme leaves.
In a small bowl, whisk together the olive oil, minced garlic, herbs, sea salt, and black pepper.
Rub the herb oil mixture thoroughly over the chicken thighs, ensuring some gets underneath the skin for maximum flavor.
Place the chicken on the prepared baking sheet and roast for 15 minutes.
While the chicken starts roasting, trim the green beans and toss them with a squeeze of lemon juice and a pinch of salt.
Remove the baking sheet from the oven, arrange the green beans around the chicken, and return to the oven.
Roast for an additional 15 to 20 minutes until the chicken reaches an internal temperature of 165°F and the skin is golden brown.
Let the chicken rest for 5 minutes before serving to allow the juices to redistribute.
